    8320 / CPU-NB clocks

    I'm wondering, is it possible to archieve 2800Mhz CPU-NB on a 8320 Vishera BE?

    It's hardly posting at 2800 MHz. I cant work with HTT either (FSB) because the CPU-NB will be out of spec when i hit 220MHz (more then 2700Mhz).

    The CPU works up to 4900Mhz IBT high & Prime95 for 4 hours stable. 5Ghz posts but hard to get stable above 1.55v. My cooling is'nt sufficient going beyond that no more.

    Not that it's needed much anyway; since i'm upgrading to Ryzen very soon the moment AM4 motherboards become more available.

    Yes, but it depends at quality of piece FX. SOme chips can hold 2800 MHz CPUNB at AIR/AIO for hard benchmarks.

    So how do i succeed a higher CPU-NB OC?

    By raising CPU-NB voltage? Chipset voltage? Any other(s) ? Increase CPU-NB Load line calibration on Crosshair Z ?

    I have'nt tested nor tried out yet. I cant find any valuable info on that as well, since most threads are about bulldozer and this is a vishera.
